通过对吉林舒兰煤矿褐煤进行人工煤化模拟实验，探讨了煤化作用中不同温阶产物组分特征、气态产物甲烷碳同位素特征及煤成油和排油情况。指出温度是引起产物变化的主要原因，煤化作用中生成的气态产物主要是非烃、饱和烃和烯烃，低温阶段以非烃为主，甲烷含量随温度增加而增加，重烃气在４００～４５０℃达最大值；模拟气甲烷碳同位素随温度升高逐渐变重；煤不但可以生油而且可以排油，排油过程在３５０℃之前就开始了，在３７５～４２５℃排油量达最大值。
Through artificial coalification simulation experiment on lignite in Shulan Coal Mine in Jilin Province, the characteristics of the product components with different temperature steps, the carbon isotope characteristics of gaseous products and the oil formation and drainage of coal are discussed. It is pointed out that temperature is the main cause of product change. The gaseous products generated in coalification are mainly non-hydrocarbon, saturated hydrocarbons and olefins. Non-hydrocarbons are the main components in the low-temperature stage. The content of methane increases with increasing temperature. Up to the maximum value; Simulated methane gas carbon isotopes become heavier with increasing temperature; coal can not only generate oil and can discharge oil, the oil discharge process begins before 350 ℃, and the oil discharge reaches the maximum at 375 ~ 425 ℃.
